I am of the opinion (but not conviction) that there was a star created to correspond to every angel, since both angels and stars are referred to as the "host of heaven." I also take Isaiah 14:12-15 as referring to the King of Babylon prophetically, but also as a flashback/forward to Lucifer's fall.
In Luke 10:18 (ESV), Jesus refers to the original fall of Satan, which seems to be directly connected to Isaiah 14:
1And he said to them, “I saw Satan fall like lightning from heaven.
Revelation 12:4 reads:
His [the dragon's] tail swept down a third of the stars of heaven and cast them to the earth. And the dragon stood before the woman who was about to give birth, so that when she bore her child he might devour it.
I take this passage to refer to the fall of Satan in the past, and therefore postulate that one-third of the angels followed Lucifer in his rebellion.
What do you think?
